Bring to the boil and simmer for 5-10 minutes before adding the coconut milk and chicken pieces. Bring to the boil again and simmer for 5 minutes, or until the chicken is cooked. Add the lime juice .

Put the noodles in serving bowls and ladle over the laksa. Serve with mint leaves, bean shoots and cucumber.
